Bug ID: 102956
Summary: Monitor loses signal when quitting Sagara Family
Product: DRI
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: f...@mt2015.com
Reproducable 100% of time.
I quit Sagara Family from main menu and monitor loses signal instead of showing
desktop. I can restore signal by lowering resolution with ARandR and then
putting 1920x1080 back.
journalctl shows this:
com.deepin.daemon.Display[6672]: manager.go:575: [updateMonitor] Set mode '115'
failed: Invalid output mode: 115
------------------
Graphics: Card: Advanced Micro Devices [AMD/ATI] Tonga PRO [Radeon R9 285/380]
Display Server: x11 (X.Org 1.19.3 ) driver: amdgpu Resolution:
1920x1080@60.00hz, 1920x1080@60.00hz
OpenGL: renderer: AMD Radeon R9 200 Series (AMD TONGA / DRM 3.15.0 /
4.12.13-1-ARCH, LLVM 5.0.0)
version: 4.5 Mesa 17.2.1
wine-staging 2.17
------------------
Arch Linux stock kernel does above mentioned behaviour. Linux
4.12.0-1-amd-staging loses signal from second monitor instead of first one as
soon as game is launched, and signal can be restored the same way.
